摘　　要：根据铸铜冷却壁的结构特点,分析了铸铜冷却壁的传热过程,重点研究了冷却壁本体与冷却水之间的传热热阻,提出了高炉铸铜冷却壁热面状况计算模型。通过采集和处理现场高炉数据,以及采用编程技术实现了该模型的在线计算,并且成功应用到了国内某钢铁公司高炉生产中。实践证明,该模型可以有效地帮助工长实时把握冷却壁热面状况,加强对炉型的管理,当发生渣皮厚度异常时,可以提早进行操作干预,有效避免了渣皮大面积脱落或者结厚,从而对于高炉顺行和高炉长寿等起到了促进作用。Abstract： According to the structural characteristics of cast copper cooling stave, the heat transfer of cast copper cooling stave was analyzed and heat transfer thermal resistances between cooling stave body and cooling water were mainly researched, and then a calculation model of blast furnace cast copper cooling stave hot surface status was put forward. The online calculation of the model was realized and practiced in the blast furnace production of a domestic steel company by the technologies of data acqui- sition, processing and programming. Practice proved that the model could effectively help foremen bet- ter understand the condition of hot surface status of the cast copper cooling stave and avoid large slag off or thick skin, so that blast furnace stability and long campaign life were promoted greatly.
